how can i set query string on ts request?

any event like ? onBeforePlay? i wanna set auth string on each ts file when request to play

public function onBeforePlay(tsFileName:String):String{
return tsFileName+"?username=test&token=fdslfj34dslfj23dslfjs32lfjds"; //like this pls
}

Start by tracing the request path associated with onBeforePlay(tsFileName:String) and determine whether it can return a TS URL with query parameters. Done means documenting or supporting a way to add the requested authentication string to each TS-file request, with the behavior verified in the relevant playback flow.
